Abstract

Methods of estimating permeability of reservoir rocks using mercury injection capillary pressure can include: receiving mercury injection capillary pressure test data and porosity data for a core sample; determining a fractal dimension (D) for the core sample based on the received mercury injection capillary pressure test data for the core sample; determining a pore throat radius (R) for the core sample; determining a composite parameter (β) for the core sample where and estimating permeability (K) of the core sample based on a relationship of ln(K) as a function of ln(β) determined by performing a regression analysis data from other core samples from the reservoir.
